如何在不使用argparser的情況下添加client_secret？

我想測試Google Genomics。我有一個項目，我可以從getting started with the api運行main.py。但這個文件皮張oauth2client的引擎蓋下的憑證是如何產生的：如何在不使用argparser的情況下添加client_secret？

import argparse 
import httplib2 
from apiclient.discovery import build 
from collections import Counter 
from oauth2client import tools 
from oauth2client.client import flow_from_clientsecrets 
from oauth2client.file import Storage 
from oauth2client.tools import run_flow 

# For these examples, the client id and client secret are command-line arguments 
parser = argparse.ArgumentParser(description=__doc__, 
    formatter_class=argparse.RawDescriptionHelpFormatter, 
    parents=[tools.argparser]) 
parser.add_argument('--client_secrets_filename', 
        default='client_secrets.json', 
        help='The filename of a client_secrets.json file from a ' 
         'Google "Client ID for native application" that ' 
         'has the Genomics API enabled.') 
flags = parser.parse_args() 

# Authorization 
storage = Storage('credentials.dat') 
credentials = storage.get() 
if credentials is None or credentials.invalid: 
    flow = flow_from_clientsecrets(
    flags.client_secrets_filename, 
    scope='https://www.googleapis.com/auth/genomics', 
    message='You need to copy a client_secrets.json file into this directory, ' 
      'or pass in the --client_secrets_filename option to specify where ' 
      'one exists. See the README for more help.') 
    credentials = run_flow(flow, storage, flags) 

# Create a genomics API service 
http = httplib2.Http() 
http = credentials.authorize(http)

有人能解釋我這是什麼碼？我怎麼能把它轉換成沒有爭論的東西？

我試着用google-api文檔的其他解決方案，但主要是我不明白正在做什麼，所以我不明白我該怎麼做。（我也不完全瞭解OAuth2client） This answer建議argparse是強制性的。但this其他方式使用google-api-python-client不要使用它...
